We shall make a basic assumption that we are interested in media which will be useful in the mainstream of instruction in the day-to-day mathematics classroom. For our purposes, new media are considered as materials which can be integrated with more conventional materials to provide a multimedia approach to the instructional-learning process in mathematics. Moreover, this discussion will be limited to communication media, which includes television, moving picture films, single concept films, projectuals, filmstrips, programmed instruction, and the like. That is, media to be used as a part of the instructional program will be that which communicates something about the concepts and principles of mathematics to the children in much the same way that the teacher or textbook communicates with them.
